Enabling and disabling in Igor Pro

Every control takes disable, and using it is how a panel explains itself.

Function SyncPanel()
    ControlInfo/W=AnalysisPanel smoothChk
    Variable smoothing = V_value

    Button runBtn, win=AnalysisPanel, disable=(smoothing ? 0 : 2)
    SetVariable thrSet, win=AnalysisPanel, disable=(smoothing ? 0 : 2)

    ControlUpdate/W=AnalysisPanel thrSet
    DoUpdate/W=AnalysisPanel
End

How it works

1. disable=0 is normal, 1 hides it, 2 grays it out.
2. Gray out what cannot apply yet rather than letting it fail.
3. ControlUpdate redraws one control after its backing value changed.
